Application filed March 18, 1907. Serial No. 363,124.

To all whom it may concern:

Be it known that ALBERT F. SCHROEDER, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, hasinvented certain new and useful Improvements in ElectroplatingApparatus, of which the following is a specification.

My invention relates to an electro-plating apparatus of the classcomprising an electro-plating tank having a rotatable receptaclesupporter therein and immersed or partly immersed in the electro-platingfluid, and adapted to receive the articles to be plated.

The objects of my invention are to provide a supporting frame havingnovel means of holding and revolving the rotatable receptacle whereby itmay be moved from the tank and the supporting frame without disturbingthe mechanism.

on another tank in a minimum amount of time.

Still further objects are to provide novel means of roparallel with theshaft 12. Shaft 15 carries thereon a pulley 16, which may be connectedto a source of power or which may be displaced and a crank substitutedto manually rotate the elements, and said shaft also carries a smallgear 17 meshing with and transmitting rotation to the gear 14 andsprocket wheel 13.

At the lower end of the casting 1 is formed an elongated opening 18through which is vertically arranged thelsorew shaft 19 rotatabletherein, but held from lon- I gitudinal displacement therefrom. Asprocket chain tating the receptacle and compensating for the wear ofthe mechanism employed and to combine the entire structure in a simple,cheap and portable device.

My invention resides therefore in the construction arrangement andoperation by going objects as hereinafter described accompanyingdrawings, in which,

and shown in the Figure 1, is an elevation of my improved apparatuslooking from below the horizontal plane thereof. Fig. 2, is an elevationof one end of the apparatus showing the same within the tank anddetachably clasped thereto. Fig. 3, is an elevation of the other end ofmydevice, and Fig. 4, is a horizontal section illustrating the manlowersprocket wheel.

Referring to the figures the inverted U shaped castings 1 and 2 form theend pieces of my improved apparatus, the same being held in spacedrelation by means of the transverse bars 3, 4 and 5 and having lateralarms 6 on which are arranged open bearings 7 for the recepand thecasting 1 is adapted to anism employed to transmit rotation to the shaft8 and drum 9 as will now be described. A bracket 11 is conwhich I attainthe fore 20 is arranged on the upper sprocket wheel 13 and drives alower sprocket wheel 21 mounted on short shaft 22. The sprocket 9mounted on the rotatable shaft 8 is arranged in the path of travel ofsaid sprocket chain and its teeth engage therewith to rotate the shaft8. It will thus be seen that by this novel way of driving the shaft 8 Iam able to lift the drum 9 and shaft 8 from the bearings 7 withoutdisturbing the other elements in the slightest. It may also be seenhowever, that after considerable wear the sprocket chain 20 is apt tobecome loose in fact so loose that the sprocket wheel 9il could notproperly engage therewith to rotate. To obviate this difficulty Iarrange the shaft 22 carrying the lower sprocket 2l adjustable in orderthat the chain 20 may loosened as desired, to compensate for wear and toallow the gear 9a to be replaced by a larger one when it is desired torotate the drum 9 slower.

The shaft 22 is provided with a square end 23 slidably arranged Withinthe opening 18 and provided with a transverse threaded opening throughwhich the screw shaft 19 is mounted. The squared end of shaft 22 is alsoprovided with shoulders 24 arranged against the inner edges of theopening 18 and with a bearing plate 25 attached to the outer end thereofby means of a bolt 26 and spanning the said opening 18 on its outeredges. Shaft 22 is further provided with a screw threaded inner endhaving a nut 27 screwed thereon to hold the sprocket wheel 21.

The operation of my device is as follows. To install the mechanism it issimply necessary to clamp the castings on the side of the tank by meansof the clamping thumb screws 10 and the clamping board same may be justas quickly and easily removed and installed in another tank after beingWashed. The

means for driving shaft 15 having been coupled thereto and started,power is transmitted through gears 17 and 14 to the sprocket wheel 13and the sprocket chain 2O in its travel about wheels 13 and 21, drivesthe sprocket wheel 9fL and consequently rotates the drum 9.

Having thus fully described my invention what I claim is,

1. In a device of the character described, a tumbling drum having acentral shaft extending axially therethrough, castings for rotatablysupporting said drum, a drivingl train and a gear wheel mounted on saidshaft and nected on the upper end of said casting l and has mountedtherein a short rotatable shaft 12 carrying a sprocket wheel 13 on oneend and a gear wheel 14 on the other end thereof. A second short shaft15 is journaled in an extension of the bracket 11 and is arrangeddetachably held against and in operative engagement with I with saiddriving train, whereby said drum may be re- 1() said driving train,whereby said drum may be removed inmoved independent of the othermechanism, substantially dependent of the other mechanism, substantiallyas deas described,
